This invention relates, generally, to an implement for cleaning windows and similar surfaces.

This invention has for its principal object to provide a novel construction of cleaning implement having a reservoir to contaln a cleansing liquid and a novel externally proj ecting means in communication with the 1nterior of said reservoir adapted to saturate with the cleansing liquid contained therein, whereby, on application of its externally projecting parts to a surface to be cleaned, the cleansing liquid may be applied upon sald surface; the device being further provlded with a novel construction and arrangement of reversible flexible wiper strip or squeegee, which may be conveniently positioned for use in wiping the surface to be cleaned so as to remove the cleansing liquid therefrom, together with the soil or dirt loosened by the latter.

The invention has for a further object to provide a novel arrangement and construction of opposed reservoir shells having a hollow rectangular fibrous pad clamped there between, together with means serving to hold said shells in assembled relation to the pad and also to provide a filling opening in communication with the interior of the reservoir formed by said shells and pad.

This invention has for a further object to provide in connection with the reservoir a novel means for so connecting the squeegee or wiper strip therewith, that the same may be disposed in various operative or inoperative positions as may be convenient or desirable.

This invention is illustrated in the accompanying drawings, in which Figure 1 is a top plan view in perspective, with the squeegee or wiper strip in one operative position; Figure 2 is a transverse vertical section, taken on line 2-2 in Figure 1; Figure 3 is a bottom plan view, with handle portion broken away; and Figure 4 is a side elevation. Figure 5 is a perspective View of the fibrous pad member of device.

Similar characters of reference are employed in all of the above described views, to indicate corresponding parts.

Referring to said drawings, the reference Serial No. 323,590.

character 6 indicates a top shell and 7 a bottom shell. These shells 6-7 are disk- The shells 6-7 are assembled respectively A on opposite sides of said pad 8, and so that their peripheral edges 9 will engage and grip into the faces of the latter.

, The shells 6-7 and pad 8, thus operatively assembled together, are retained in such assembled by a bolt member 10. Said bolt member 10 is provided adjacent to one end with an external annular stop shoulder 11, and at its other end with an externally threaded shank 12 of reduced diameter, so as to form therewith a shoulder 13. The shell 6 is provided with a central opening corresponding to the diamter of the bolt 10; and the shell 7 is provided with a central opening corresponding to the diameter of the shank 12. The bolt extends through the top shell 6 until stopped by the external shoulder 11, a gasket 14 being interposed between the shoulder 11 and exterior surface of shell 6 to provide a liquid tight joint. The shank 12 of the bolt extends through the bottom shell 7, a gasket 15 being interposed between the shoulder 13 and the interior surface of said shell 7 to provide a liquid tight joint. A fastening nut 16 is screwed on the exte- 'riorly projecting end of the shank 12 to hold the parts in the thus assembled relations.

Said bolt member 10 is provided with an axial intake opening 17 entering the body of the same from its upper end, and is further provided with a lateral opening 18 affording commimication between said axial opening 17 and the interior 19 of the reservoir formed by the assembled shells 67 and pad 8. The upper end portion of said bolt member 10 is externally threaded to receive a closing cap 20 for closing the outer end of the axial opening 17 thereof. It will be obvious that said axlal openin 17 and lateral opening 18 together provide a filling passage through which a cleansing liquid may be introduced into the interior 19 of the reservoir.

The lower shank end of said bolt member 10 is adapted to receive attachment of a handle element 21 for holding and manipulating the device. This handle may be screwed on to the end shank 12, or the latter may be provided with an internally threaded opening or socket, and the handle element may be provided with a threaded stud 22 to screw into said socket, as shown in Figure 2.

The squeegee or wiper stri device comprises a body or strip 23 of ru ber, or material of similar characteristics, clamped between a pair of longitudinal rigid carrier bars 24, of less width than that of the body or strip 23, so as to leave the longitudinal marginal portions of the latter, at both sides thereof, free and flexible. The carrier bars 24 and wiper body or strip 23 may be secured together by any suitable fastening means 25, such as bolts, screws, rivets or the like. The Wiper stri or body 23 is connected with the reservoir evice so as to be disposable in various positions by the following means. Engaged on the shank 12, between the exterior surface of the shell 7 and the fastening nut 16, is a swivel plate 26, having diametrically andoppositely extending arms 27 which terminate in upstanding perforate ears 28. One of the carrier bars 24 of the squeegee device is also provided with spaced apart perforate ears 29 in which is journaled the main body 30 of a bail, the respective arms 31 of which extend to and are pivotally connected with the perforate ears 28 of said swivel plate 26 by means of journal extensions 32 which project from the extremities of said arms 31. From the above description and an inspection of the drawings, it will be obvious that the squeegee or wiper strip may turn in transverse plan about the axis of the central bolt 10 and handle 21, due to the swiveling relation existing between the swivel plate '26 and shank 12, and, also, said squeegee or wiper strip is also capable of swinging movement on the fulcruming journal extensions 32 of the bail.

In the use and operation of the device, a cleansing liquid, such e. g. as Water, is introduced into the interior 19 of the reservoir through the filling openings 17-18, which are thereupon closed by the cap 20. The water will saturate the body of the pad 8 by virtue of its contact with the inner portions of the latter. The operator now grasps the handle 21, and allowing the wiper strip to hang down, may apply any portion of the exterior parts of the pad 8 to the surface to be cleansed, and by rubbing the latter therewith, may thus cause the cleansing liquid, with which it is saturated, to spread 011 said surface so as to loosen the dirt thereon. After thus moistcning the surface to be cleaned, the wiper strip 23 is raised until it abuts the reservoir, in which position one edge thereof is projected beyond the external periphery of the pad. When thus positioned the wiper strip may be moved over the surface to be cleaned to remove the water and loosened dirt therefrom in the usual manner. It will be obvious that the wiper strip may be turned on its swivel connection so as to cooperate selectively with either side of the pad; and the wiper strip may be reversed so as to utilize either longitudinal edge thereof.

From the above description it will be ap parent that the present invention provides a very simple and yet efiicient cleaning implement, which provides a maximum amount of moistening pad material, as well as a novel arrangement and relation of squeegee element in combination therewith.

I am aware that various changes may be made in the arrangements and combinations of the devices and parts, as well as in the details of the construction of the same, without departing from the scope of this invention as set forth in the foregoing specification and as defined in the appended claims. Hence, I do not limit my invention to the exact arrangements and combinations of the several devices and parts as described in the foregoing specifications, nor do I confine myself to the exact details of the construction of said parts as illustrated in the accompanying drawings.

I claim 1. In a device of the kind described, a pair of similar substantially concavo-convex shells having their open sides opposed one to the other, a saturatable unitary pad having an open center portion interposed and gripped between the margins of said shells so as to both project exteriorly from the latter and into the space therebetween, a central bolt device for holding said shells and pad in assembled relation whereby an interior reservoir chamber is provided to supply liquid to said pad, said bolt having a longitudinal passage extending thereinto from one exterior end and a lateral passage leading therefrom into the reservoir chamber, a removable cap for closing the outer end of said longitudinal passage, and a handle member connected with the opposite end of said bolt.

2. In a device of the kind described, a pair of similar substantially concavo-convex shells having their open sides opposed one to the other, a saturatable unitary pad having an open center portion interposed and gripped at its sides between the margins of said shells so as to both project exteriorly from the latter and into the space therebetween, a central bolt device having a shoulder on one end portion and nut means on its other end portion for holding said shells and pad in assembled relation whereby a reservoir chamber is provided to supply liquid to said pad, said bolt having a longitudinal passage extending thereinto from one exterior end and a lateral passage leading therefrom into the reservoir chamber, a removable cap for closing the outer end of said longitudinal passage, a handle member connected with the opposite end of said bolt.

In testimony that I claim the invention set forth above I have hereunto set my hand this 28th day of November, 1928.
